The 11th Conference on Telecommunications - ConfTele 2019, organized by the Telecommunications Specialization (Colégio de Engenharia Eletrotécnica) of Ordem dos Engenheiros and Instituto de Telecomunicações, will be held in the Headquarters of Ordem dos Engenheiros, Lisbon, Portugal, on June 26, 27 and 28, 2019. The theme of this year’s conference is "Telecommunications Technologies Pursuing New Ways of Living and Travelling”.
The Conference includes plenary sessions with invited keynote speakers and talks, parallel thematic sessions (including regular oral and poster presentations), interactive sessions on the discussion of previously published papers, tutorials and exhibition.
All contributions must be electronically submitted by April 12, 2019, as 3/4-page full papers in PDF format according to the template provided at the Conference website. Please refer to the website for further submission details. At least one of the authors of accepted papers is required to be registered by June 5, 2019.

Date & time: Tuesday, June 4th, 15:00h
Location: Amphitheatre of the Instituto de Telecomunicações - Pólo de Aveiro, Building 19
Deep traps responsible for nonradiative recombination in GaN films, in green, blue, NUV LEDs, both as-grown and subjected to electron irradiation or to long time operation, will be discussed. Possibilities arising from nanopillar structures formation and interaction with localized surface plasmons will be described. Deep traps in the barriers and buffers of AlGaN/GaN, InAlN/GaN HEMTs giving rise to long-time gate and drain current transients will be analyzed, approaches to treatment of non-exponential current relaxations originating in variations of local electric field strength, local potential fluctuations will be described.
Since 2014 he is a Professor at the Department of Semiconductor Electronics and Physics of Semiconductors of the National University of Science and Technology “MISiS” in Moscow and Head of the laboratory "Wide-Bandgap Semiconductors and Devices" at this university. He is an author or co-author of more than 300 research papers, 2 monographs, multiple invited chapters in books on III-V semiconductors, and multiple review articles. His areas of expertise include deep traps in compound semiconductors, properties of heterojunctions and quantum wells, hydrogen passivation effects, radiation defects studies, interaction of III-N LEDs with localized surface plasmons.
